Brake Shoe: Testing and Inspection
BRAKE LINING THICKNESS CHECK CAUTIONCAUTION:
^ Whenever the shoe and lining assembly is replaced, replace both RH and LH assemblies as a set to prevent the car from pulling to one side when braking.
^ If there is a significant difference in the thickness of the shoe and lining assemblies on the left and right sides, check the sliding condition of the piston.
NOTE: For brake lining thickness for drum-in-disc brake, refer to Parking Brake Drum.
1. Remove the brake drum.
2. Measure the thickness of the brake lining at the area with the worst wear.
Standard value: 4.9 mm (0.19 inch)
Minimum limit: 1.0 mm (0.04 inch)
3. Replace the shoe and lining assembly if the brake lining thickness is less than the limit or if it is not worn evenly.
